HOG-SCALDING APPARATUS.

PatentedNov. 25, 1913.

Application led April 25, 1913. Serial No. 763,617.

This invention comprehends improve? ments in ho-g scalding apparatus and has for its primary object the provision of simple means whereby a hog may be easily turned over within a scalding tank.

Another and more specific object of the invention is to provide an apparatus including. two endless chains secured to rollers carried adjacent the side of a tank, said chains being adapted to support a hog and? turn the same when properly actuated.

The invention also aims to generally improve apparatus of this type to render the same more eiiicient', more easily operated, and mo-re commercially desirable.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, aswill be hereinafter described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a top plan view of a hog scalding apparatus constructed in accordance with my invention, Fig. 2 is a vertical transverse sectional view therethrough, taken on the plane of line 2-2 of Fig. 1, Fig. 3 is a detail view taken on the plane of line 3-3 of Fig. 1, and Fig. 4 is a section taken on the plane of line t-l of Fig. 2.

Referring in detail to the drawings by numerals, 5 designates a hog scalding tank, of any preferred construction. In the preferred embodiment of my invention, I provide brackets, generally designated 6, and each formed of a strip of flat metal bent intermediate its ends to provide a pair of essentially parallel arms which vare adapted to engage opposite faces of one of the side walls of the tank. Set screws 7 are employed for the purpose of securing the bracketsin` position. A shaft 8 is journal'ed 'through the brackets and is adapted to be rotated byv means of a crank handle 9 secured to one end thereof. A ratchet wheel 10 is rigid with the shaft and is engaged by a pawl 1-1, which' holds the shaft against rotation in one direction. Toothed rollers 12 and 13 are slidably secured to the shaft 8 by means of pins 14 which project into groovesl15 formed therein. It will be noted that these rollers are of a peculiar construction, being' formedI with relatively deep peripheral channels having teeth formed' upon the inner walls thereof. A second shaft 16 is secured upon the opposite side of the tank in parallel relationship to the shaft 8 by means of vertically adjustable brackets 17. These brackets are apertured at their enlarged upper ends to permit the passage therethrough of the shaft and are provided with Shanks 18 which are formed with a plurality of vopenings 19. These shanks are slidable within dove-tail grooves 2O formed in th'e inner arms of Ushaped members 21, which are secured to the side of the tank by means of set screws 22. The side walls of the grooves 20 are apertured as indicated at 20', to receive lockingpins 21" which, by

extending through certain of the openings rinA t-he'shanks 18will support the latter in any desired position. RollersI 23 and* 24g A similar' in construction to the rollers 13 but of a somewhat larger diameter, are slidably secured to the shaft 16 by means of pins 25 which project into slots 26. A pair of endless chains 27 and 28 run around corresponding rollers upon opposite sides of the tank, and pass transversely through the tank, as clearly shown in Fig. 2.

In operation, a hog is placed across the upper leads of the chains, said chains having been first adjusted so as to have the proper dist-ance between them and then the shaft 8 is rotated by means of the crank handle 9. This rotation of the shaft will cause the chains to run through the tank and they will serve to roll the hog over. When it is desired t0 raise the hog to the top of the tank,

'pins are inserted through certain of the openings 29 in the smaller rollers 12 and 18 so as to prevent the chains running over the same, and then by turning the crank handle, the chains will be brought into essentially horizontal planes above the top of the tank. The .ratchet wheel u10 and pawl 11 prevent a reverse'rotation of the shaft 8 and it will therefore be seen that a hog Will be supported vupon the upper leads of the VVchains above the tank. The distance to which the chains descend into the tank may be regulated by raising or lowering the brackets 17.

From the foregoing description taken in connection with the accompanying drawing, it will be seen that I have provided a hog scalding apparatus of extremely simple construction, which may be easily operated by one person so as to lower a hog into the scalding tank, turn the same over therein, and then raise it above the tank.

It is` to be understood that while I have shown and described the preferred embodiment of my invention, I do not wish to be limited `to this exact construction, combination, and arrangement of parts, but may 'make such changes as will fall Within the spirit and scope of the'invention.

Having thus described my invention, what I claim is l. In a hog scalding apparatus, the combination with aswinging tank, of a shaft rotatably secured to one side thereof, rollers rigid With said shaft and formed with peripheral channels having teeth formed upon the inner walls thereof, the side walls of said channels being formed with registering openings, means for rotating said shaft, vmeans for locking the shaft against rotation in one direction, a second shaft rotatably supported upon the other side of the tank, grooved rollers rigidly secured to the second mentioned shaft, endless sprocket chains running over corresponding rollers on the two shafts, and means adapted to be inserted through the registering openings in the first mentioned rollers to prevent the chains running around said rollers.

2. In a hog scalding apparatus of the character described, a swinging tank, a shaft rotatably secured to one side thereof, means fo-r rotating said shaft, means for locking the shaft against rotation in one direction, a plurality of rollers rigidly secured to the shaft and provided with peripheral channels having teeth formed upon the inner wall thereof, the side walls of said channels being provided with openings, a second shaft rotatably secured to the other side of the tank, rollers rigidly secured to the second mentioned sha ft, endless sprocket chains running over corresponding rollers on opposite sides of the tank, and pins inserted through the openings in the side Walls of said channels to lock the chains against movement relative to the corresponding rollers.

3. In a hog scalding apparatus, the combination with a scalding tank, of a shaft supported upon one side thereof, means for rotating said shaft, means for locking the shaft against rotation in one direct-ion, a second shaft secured to the other side of said tank, toothed rollers rigid With the shafts, endless chains revoluble around corresponding rollers and running through the tank, and means for locking the chains to certain of the rollers, whereby the chains may be drawn taut.

In testimony whereof I aiix my signature in presence of two witnesses.
